RONKONKOMA - The Long Island Rail Road (LIRR) has rolled back its on-time performance numbers following an outcry from commuter advocates.

Early last week, officials said trains were on time 91.9 percent of the time in November although the LIRR canceled 3,500 trains and announced numerous delays. Now, they're saying trains were on time 88.1 percent of the time after the LIRR Commuters Campaign challenged the numbers.

After Sandy, LIRR officials say they changed the official definition of a late train from one that is more than six minutes late to one that is more than 16 minutes late. They say the change was justified because the LIRR warned commuters to expect delays.
